Cogburn

It's been some time but I was wondering if you are still working on this project? I appreciate the detail you posted and wanted to know if you made any other progress with the CB750F? I have a 81' CB900F and just started working on the swing arm. I noticed you have the NC31 version which is longer. I just bought an NC39 which I hear is 52cm +/- 1cm from the pivot to the axle centerline. Maybe this can be an option for you? Also have a CB1000SF (Big1) swing arm but that puppy is long and wide.
